Overview
Ranch dressing is a savory, creamy American salad dressing usually made from buttermilk, salt, garlic, onion, mustard, herbs (commonly chives, parsley and dill), and spices (commonly pepper, paprika and ground mustard seed) mixed into a sauce based on mayonnaise or another oil emulsion. Sour cream and yogurt are sometimes used in addition to, or as a substitute for, buttermilk and mayonnaise.
Ranch has been the best-selling salad dressing in the United States since 1992, when it overtook Italian. It is also popular in the United States and Canada as a dip, and as a flavoring for potato chips and other foods. In 2017, 40% of Americans named ranch as their favorite dressing, according to a study by the Association for Dressings and Sauces.
History
In 1949, Thayer, Nebraska native Steve Henson (1918–2007) moved with his wife to the Anchorage, Alaska, area, where he worked as a plumbing contractor. While there, he invented a new salad dressing.
Henson retired from plumbing at age 35, and moved with his wife to Santa Barbara County, California. In 1956, he purchased a guest ranch in San Marcos Pass and renamed it Hidden Valley Ranch.
